Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to a medical bandage
and, in particular, to a deformable, cap-shaped medical dressing or
bandage conveniently shaped to cover a wound on a patient's head,
limb, stump, finger or other body part for emergency,
post-surgical, or chronic wound care, for instance in the event of
a bleeding cranial wound or in the event or curing an amputated
limb. The present invention provides access ports to the wound in
order to support or stabilize wound drains, or apply medicine to
the wound.
BACKGROUND OF THE INVENTION
[0002] Typically, a medical bandage or dressing is a covering or
wrap that protectively conceals a wounded area of the body in order
to stem the flow of body fluids from the wound, absorb body fluids
from the wound, ease pain, debride the wound, protect the wound
from infection, promote healing of the wound, and/or reduce
psychological stress. Medical bandages are used for many different
healthcare situations such as for emergency, post-surgical, or
chronic care of a wound. Normally, bandages or dressings are in
direct contact with the wound, and are covered with an adhesive
film to hold them in place. Dressings can be marketed in various
configurations; in a first example, dressings are sold alone in
rolls, sheets or pads, to be directly applied on or around a body
portion; in another example, a dressing and a corresponding
adhesive band are sold as an integral product. Generally, dressings
are sold in a flat configuration, to cover a substantially flat
surface of the body. In the event that a curved surface is to be
covered, the dressing is deformed to adopt the shape of the
surface. Similarly, in the event that a full perimetric surface
must be covered, such as a wrist or knee, the dressing is deformed
to wrap around the perimetric surface.
[0003] It is well known that traumatic amputations are generally
gruesome, devastating injuries that may result in death. Similarly,
head injuries often result in trauma to the scalp, skull, or brain.
These injuries frequently result in extreme blood loss which can
contribute greatly to the associated fatality rate. The time
required to control the bleeding of an amputation is vital in
reducing blood loss. Often, quickly covering the wounds on the
amputated limb or head helps to stop further blood loss during
emergency care, and maintaining a suitable bandage can help protect
the wound, promote wound healing and prevent infection. However,
the dressing and bandage materials known in the art are often
cumbersome to handle and difficult to appropriately deform and
apply, particularly on an immobilized victim. Due to different
settings, injuries, and access to care, medical professionals must
use a multitude of sizes, shapes, styles of bandages for covering
and treating wounds of the head or limb. In consequence, it is not
rare that medical professionals are required to heavily manipulate
dressings in order to fit them onto the head or onto a stump,
leading to a great loss of time and to an increased risk of the
dressings being contaminated or placed ineffectively from such
manipulation. A person skilled in the art will clearly understand
that the more ready, intuitive, and universally applied the medical
devices and instruments are, the more effective and successful the
treatment can be for immediate medical and post-traumatic wound
care. In addition, promoting wound healing of the head or a limb
can be a lengthy process requiring days to months of dressing
changes and wound care. Having to repeatedly and manually wind and
unwind conventional dressings (not particularly indicated for the
head or limb) over the head or limb is cumbersome and extremely
labor consuming.
[0004] In an attempt to reduce the amount of time needed to obtain
a covering that is specifically shaped for the patient's head, some
head-specific bandage solutions have been developed. For instance,
U.S. Pat. No. 5,031,609 describes a postoperative compression
bandage for the head which is formed of two identical flat portions
affixed to one another forming a flat body, wherein the body can be
wrapped around the patient's head and be secured in place by
hook-and-loop fasteners comprised on certain edges of the flat
portions. U.S. Patent Application No. 2009/0299259A1 describes a
head trauma cap bandage and method which, when applied, applies
compression pressure to stop bleeding; the head trauma bandage is
cap-shaped and secured to the patient's head by a strap that wraps
around the patient's mandible. U.S. Pat. No. 7,887,501 teaches a
compressive head dressing comprising an elastomeric layer and a
cinch for adjusting to the patient's head.
[0005] However, known solutions mainly focus on providing a
head-shaped dressing and do not specifically address other problems
such as being able to rapidly and efficiently provide treatment of
head wounds.
[0006] Accordingly, there remains a need in the art to provide an
adequate dressing cover for the head, a limb or a stump or an
extremity of the human or animal body, which is optimized for such
body part, facilitates treatment of wounds and is yet provided at
reasonable cost.
SUMMARY OF THE INVENTION
[0007] The present invention overcomes the deficiencies of the
known art and the problems that remain unsolved by providing a
medical bandage specifically designed for the head, a limb, a
stump, a finger or other body part, producing a dressing covering
that can be rapidly, intuitively, and universally applied in the
event of an emergency or trauma. Unlike conventional dressings, the
medical bandage disclosed herein can open for rapid easy fitting
without further traumatizing a head with patient supine. In
addition, the medical bandage disclosed herein is useful for
treating ongoing wound care needs, to stabilize and hold drains,
view wounds, medicate, and allow for a rapid and universal dressing
change which is designed for use for both the head and a limb, as
well as other body parts.
[0008] The medical bandage presents a three-dimensional cap-like
shape having a convex outer surface and a concave inner surface
configured to conform to the head, limb, stump, finger or other
body part. The medical bandage is formed by several layers of
material, namely an internal layer made of a soft, skin compatible
fabric, an external layer made of breathable material, and an
intermediate absorbent layer or, alternatively or complementarily,
an intermediate flexible bladder. Means of adjustment such as side
hook-and-loop straps can be included in order to adjust the bandage
to the head, limb, stump, finger or other body part and provide
necessary compression to coagulate and maintain an intact dressing
to cover the wound and promote healing. In some embodiments, the
bandage can be partially or totally elastic to provide adjustment.
In some embodiments, the medical bandage not only provides a
ready-to-apply cover for a wound, but also includes active treating
agents such as coagulant agents, antimicrobial agents, heating
agents, cooling agents, or a combination thereof. The medical
bandage in accordance with the invention may be used not only to
cover wounds, but also for other purposes such as treating or
preventing hair loss.
[0009] In a first implementation of the invention, a medical
bandage comprises a deformable main body having an inner surface
and an outer surface. The main body is configured to adopt a
position in which an inner cavity is delimited by the inner surface
for at least partially receiving a head, limb, stump, finger or
other body part. At least part of the main body comprises a
skin-compatible first layer, a second layer and a non-permeable
third layer. The first layer is arranged closer to the inner cavity
than the third layer. In turn, the second layer is arranged between
the first layer and the third layer and comprises at least one
space through which the first and third layers directly face one
another. The main body of the bandage further includes at least one
through port arranged at the at least one space, for accessing the
inner cavity of the main body from outside the main body and
through the first, second and third layers, or for stabilizing or
supporting a drain or tubing passing through the port.
[0010] In a second aspect, the at least one through port can be
provided by scored lines and can adopt a closed position in which
the scored lines are not torn, and an open position in which the
scored lines are torn open providing quick access to the inner
cavity.
[0011] In another aspect, the second layer can include an absorbent
material, and the first layer can be permeable to the passing of
fluid from the inner surface towards the second layer.
[0012] In another aspect, the main body can further include at
least one adjustment strap, configured to adjustably attach two
different sections of the main body.
[0013] In another aspect, the adjustment strap can be fixedly
attached to a first section of the main body and disconnectably
attachable to a second section of the main body.
[0014] In another aspect, opposite ends of the adjustment strap can
be disconnectably attachable to different sections of the main
body. For instance and without limitation, the adjustment strap can
be disconnectably attachable to the main body by a hook-and-loop
connection.
[0015] In another aspect, the main body can define a rim delimiting
an opening for inserting a head, limb, stump, finger or other body
part therethrough towards the inner cavity of the main body. The at
least one adjustment strap can be attachable along the rim and
parallel to the rim.
[0016] In another aspect, the at least one adjustment strap can
include two adjustment straps configured to wind with one another
and attach to the main body by a respective hook-and-loop
connection.
[0017] In another aspect, the at least one adjustment strap can
include two adjustment straps configured to tie to one another into
a knot for compression or securing the bandage.
[0018] In another aspect, at least one of the first, second and
third layers can include an insulating material such as, but not
limited to, biaxially-oriented polyethylene terephthalate (e.g.,
Mylar.RTM.).
[0019] In another aspect, the main body can be at least partially
elastic to adjustably fit onto a head, limb, stump, finger or other
body part.
[0020] In another aspect, the first, second and/or third layers can
include a plurality of partial portions, which are arranged
adjacently to each other forming a cap-shape.
[0021] In another aspect, at least two partial portions of the
second layer can be separated by a gap, through which the first and
third layers directly face one another.
[0022] In another aspect, the first layer and third layer can
include at least one pair of perforated seams facing the gap.
[0023] In another aspect, the plurality of partial portions can
include an elongated body portion and two opposite side portions
attached to opposite sides of the elongated body portion. One or
both of the opposite side portions can be pivotable relative to the
elongated body portion and configured to adopt a closed position in
which the side portions and elongated body portion form a
cap-shaped body.
[0024] In another aspect, the main body can include a tearable
portion which is configured to be torn off and removed from a
remainder of the main body to reduce the height of the main body.
The tearable portion, once torn off and removed from said remainder
of the main body, is usable as a tourniquet.
[0025] In another aspect, the medical bandage can further include
at least one sensor for measuring a body condition. The sensor can
be carried by the main body and configured to establish wired or
wireless communication with an external electronic device for
transmitting a measurement to the electronic device.
[0026] In another aspect, the at least one sensor can be
disconnectably attachable to the at least one through port.
[0027] These and other advantages of the invention will be further
understood and appreciated by those skilled in the art by reference
to the following written specification, claims and appended

[0054] The illustration of FIG. 1 presents a first exemplary
embodiment of a medical bandage 100 in accordance with the
invention. The medical bandage 100 comprises a main body 110 that
is in shape of a cap. The main body 110 presents a concave, inner
surface 120 delimiting a head-, limb- or stump-receiving cavity
122, and a convex, outer surface 124, where the inner and outer
surfaces 120, 124 converge in a perimetric rim 126. The main body
110 further presents a front side 130, a rear side 132, a right
side 134 and a left side 136.
[0055] Several layers and materials form the main body 110, namely
a skin-compatible first layer 140, an absorbent second layer 150,
and a breathable, non-permeable third layer 160, as shown in the
general perspective view of FIG. 1 and in the enlarged, exploded
view of FIG. 6. The first layer 140 and second layer 150 can be
manufactured, for instance, from cloth, gauze, cotton,
polyurethane, or a combination thereof. The third layer 160 can be
manufactured, for instance, as a polyethylene film. For better
understanding of the layered arrangement, an illustrative and
imaginary cut-out (indicated with letter A) has been carried out in
the third layer 160 of FIG. 1, unveiling the inner first and second
layers 140, 150. As shown, the first layer 140 is arranged closer
to the inner surface 120; in the present embodiment, in particular,
the first layer 140 is in fact the innermost layer, and thus the
innermost surface of the first layer 140 provides the main body
inner surface 120. In turn, the third layer 160 is arranged closer
to the outer surface 124; in the present embodiment, in particular,
the third layer 160 is in fact the outermost layer, and the
outermost surface of the third layer 160 provides the main body
outer surface 124. The second layer 150 is arranged between the
first layer 140 and the third layer 160; the second layer 150 of
the present embodiment is, in fact, arranged immediately between
the first layer 140 and the third layer 160. Thus, the main body in
accordance with the invention can comprise three or more layers,
the main body 110 of the present embodiment specifically consisting
of three layers 140, 150, 160. In addition, the first layer 140 is
permeable to the passing of fluid from the inner surface 120
towards the absorbent second layer 150, while the non-permeable
third layer 160 keeps liquids and optionally gasses within the
absorbent second layer 150. All layers 140, 150, 160 can have a
variable thickness. The first and second layers 140, 150 can have a
variable permeability and absorbency. The second layer 150, in
particular, can be manufactured having different thicknesses in
order to provide a variable degree absorbency and cushioned feel
and wound-healing properties.
[0056] As shown in FIG. 1, the medical bandage 100 can further
include one or more adjustment straps 180, each configured to
adjustably attach to two different sections or zones of the main
body 110, and provide compression if needed. The one or more straps
can be arranged in a variety of directions. In the present
embodiment, for instance, the medical bandage 100 includes two
straps 180, wherein each strap 180 is arranged from the main body
rear side 132 to the main body front side 130, extending along the
right side 134 and left side 136, respectively. Being able to
adjust the level of tightness with which the two straps 180 are
attached allows adjusting the size of the cap-shaped main body 110
to different head, limb or stump sizes, and applying needed
pressure or coverage to help stop bleeding, keep the bandage
secure, and protect the wound, thereby promoting wound healing and
assisting in post trauma/surgical care.
[0057] In the present embodiment, a first end 182 of the adjustment
straps 180 is fixedly or non-disconnectably attached to the main
body rear side 132 and an opposite second end 184 is disconnectably
attachable to the main body front side 130. Thus, the straps 180
are permanently attached to the main body 110, preventing the
straps 180 from being inadvertently lost when their second end 184
is detached from the main body 110, and yet are easily and rapidly
detachable to readjust the fitting of the cap on a head or
limb.
[0058] In the present embodiment, the straps 180 are disconnectably
attachable to the main body 110 by a hook-and-loop connection
formed by a first hook-and-loop element 190 forming part of the
strap 180 and a compatible second hook-and-loop element 192
included in the main body 110 and configured to attach to the first
hook-and-loop element 190. A hook-and-loop connection is
advantageous in that it is easy and rapidly connected and
disconnected, provides a secure and resistant attachment, and is a
cost-effective solution. In addition, it can be easily and rapidly
tightened in the event that a greater pressure (or even a
tourniquet effect) is required on the wound; similarly, the
hook-and-loop connection can be easily and rapidly loosened in the
event that an excessive pressure is being applied that is causing
discomfort in the patient.
[0059] Furthermore, the straps 180 of the present embodiment are
arranged to extend along the right side 134 and left side 136,
respectively, generally along the rim 126 and parallel to the rim
126. Thus, when the straps 180 are relatively tightly fastened to
provide a snug fitting of the cap onto the patient's head or limb,
the straps 180 provide a uniform pressure along a substantial
length of the rim 126. In consequence, the adjusted bandage 100 is
very safely secured and yet does not cause discomfort to the
patient.
[0060] Alternative embodiments of the invention can comprise a
different number of straps. In addition, in different embodiments
of the invention, one or more straps can have both opposite ends
disconnectably attachable to different sections of the main body,
instead of having one end permanently affixed to the main body. In
further embodiments, the main body can be at least partially
elastic to adjustably fit onto a head, a limb or a stump. For
instance, the first and/or third layers 140, 160 could be provided
with an elastic band along the cap-shaped main body rim 126 so that
the area of the rim 126 tightly (but comfortably) adjusts to the
head, limb or stump while the rest of the main body 110 is more
loosely fitted. In another example, the entire first layer 140
and/or third layer 160 can be elastic, to provide a compressive
effect on the head, limb or stump that can be convenient for
stopping wound bleeding or other applicable medical needs. In
general, it is contemplated that the bandage 100 can be configured
to snugly fit onto the head, limb or stump, in order for the first
layer 140 to contact the wound, or to be more loosely arranged so
that the first layer 140 does not contact the wound.
[0061] The bandage in accordance with the invention includes at
least one port providing selective access to the cavity from
outside the bandage. A nurse or other medical professional can thus
easily insert a needle, tube or other medical device through the
port, without having to reposition or remove the bandage from the
patient's head or limb. A tube can be supported by a port, or
repositioned from one port to another, without requiring the use of
tape. For example, the present embodiment provides two elongated
through ports 112 and two punctual or discrete through ports 114.
The discrete through ports 114 allow for a rapid and adjusted
insertion of the syringe or tube at specific, predetermined spots.
The elongated through ports 112, instead, allow the medical
professional to select where along the elongated port 112 to insert
the syringe or tube, permitting a more versatile and personalized
treatment.
[0062] The elongated through ports 112 of the present embodiment
are constructed by having the first and third layers 140, 160
include two respective scored or perforated elongated seams 142,
162 arranged aligned or in registration and that can be quickly and
rapidly torn or opened in order to apply a medicine onto, disinfect
or treat a wound, or visually inspect the wound; the second layer
150 can comprise a similar scored or perforated seam in
registration with the elongated seams 142, 162 of the first and
third layers 140, 160 or, alternatively, as shown in FIG. 1, the
second layer 150 can include two respective elongated channels or
spaces 152 through which the first and third layers 140, 160, and
more particularly elongated seams 142, 162, face each other
directly.
[0063] In turn, the discrete through ports 114 are formed by two
respective aligned perforated openings 144, 164 located at the end
of the perforated seams 142, 162 of the first and third layers 140,
160 and in registration with the corresponding space 152 of the
second layer 150. One or both openings 144, 164 can be scored or
perforated X-cut openings, as shown, or present any other
applicable shape such as an O-shape. In addition, alternative
embodiments are contemplated such as having aligned openings on all
three layers 140, 150, 160. It is also contemplated that an opening
on the outer, third layer 160 can be initially closed or sealed and
only accessible therethrough when ripped or perforated, while an
opening on the first and/or second layer 140, 150 can be initially
open and readily accessible once the opening on the third layer 160
is ripped or perforated.
[0064] Preferably, any one of the first layer 140, the second layer
150 and the third layer 160 can be formed of a plurality of partial
portions, arranged adjacent to one another in order for the layer
to adopt a three-dimensional cap shape. For instance, as best shown
in FIGS. 2 and 3, the second layer 150 of the present embodiment is
formed by one longitudinal partial portion 154, which is configured
to extend form a frontal area to an occipital area, and two
separate opposite side partial portions 156. Such a construction is
cost effective as it utilizes a minimum amount of flat-shaped
partial portions (as best shown in FIG. 3) to build a
three-dimensional cap-shaped second layer 150. The longitudinal
partial portion 154 is rectangular, and the opposite side partial
portions 156 are semicircular, all of which being simple shapes
that may be manufactured at reasonable cost.
[0065] As can be observed in FIG. 1, the present embodiment is such
that the elongated spaces 152 of the second layer 150 are carried
out as respective gaps that have been left between adjacent partial
portions 154, 156. Thus, perforation of the second layer partial
portions 154, 156 manufacturing the product is avoided, and the
cost of manufacture is kept reasonable. The three partial portions
154, 156 of the second layer 150 are kept in place by the first and
third layers 140, 160. Optionally, an adhesive, stitching, scoring
or the like can be applied to further maintain the relative
position of the three layers 140, 150, 160. Any seams can be
constructed so that they can be relatively easily torn, allowing
for easy dressing changes.
[0066] The absorbent, second layer 150 can further include at least
one coagulant agent, such as clay-based coagulants (kaolin,
chitosan, talc), synthetic coagulants (e.g., polymers),
animal-based coagulants (e.g., gelatins), plant-based coagulants
(e.g., cellulose) or a combination thereof, preferably embedded in
the absorbent layer material or applied on the absorbent layer
material. In such an event, the first layer 140 is configured to be
permeable for the outward passing of the coagulant agent towards
the main body inner surface 120 and the cavity 122. In alternative
embodiments, at least one coagulant agent can be included in the
first layer 140, in closer proximity to the wound.
[0067] Alternatively or additionally, the absorbent second layer
150 can include at least one antimicrobial agent, such as zincs or
silvers, in order to prevent bacterial, fungal or parasite
infection of the wound. The antimicrobial agent is preferably
embedded in the absorbent layer material or applied on the
absorbent layer material. The first layer 140 can then be permeable
for the outward passing of the antimicrobial agent towards the main
body inner surface 120 and the cavity 122. In alternative
embodiments, at least one antimicrobial agent can be included in
the first layer 140, in closer proximity to the wound.
[0068] The absorbent second layer 150 can include at least one
heating (exothermic) agent and/or at least one cooling
(endothermic) agent, such as a metal oxide, ureas, citric acid,
bicarbonates or a combination thereof, in order to prevent heat
loss from the head, limb or stump. The heating agent and/or cooling
agent is preferably embedded in the absorbent layer material or
applied on the absorbent layer material. The first layer 140 can be
permeable for the passing of the at least one heating agent and/or
cooling agent through the first layer 140 and towards the main body
concave, inner surface 120 and the cavity 122. In alternative
embodiments, at least one heating agent and/or cooling agent can be
included in the first layer 140, in closer proximity to the
wound.
[0069] Alternatively or additionally, the bandage 100 can include
an insulating material such as, but not limited to,
biaxially-oriented polyethylene terephthalate (e.g., Mylar.RTM.).
Alternatively or additionally, the bandage 100 can include adhesive
and/or petroleum.
[0070] In some embodiments, the medical bandage is packaged clean
and sterile and intended for single use only, whereas in other
embodiments the medical bandage is a multi-use, washable bandage
which can be subjected to cleaning and sterilization.
[0071] In summary, the invention provides a cap-shaped bandage
capable of being fitted on a head, a limb or a stump, and even onto
a toe, a finger, a sexual organ or other appendage of the human or
animal body, comprising an inner skin-compatible layer capable of
allowing body fluids from the wound to pass through, an
intermediate absorbent layer capable of absorbing the body fluids,
and an external breathable non-permeable layer for concealing the
absorbent layer, retaining fluids within the absorbent layer and
providing a clean finish to the bandage. In addition, the
cap-shaped bandage includes at least one port for accessing the
bandage inner cavity from the outside. The medical bandage 100 may
be efficacious for a variety of therapeutic functions, including,
without limitation, stemming the flow of body fluids, absorbing
body fluids, easing pain, debriding the wound, protecting from
infection, promoting healing, and reducing psychological
stress.
[0072] For instance, the illustration of FIG. 4 shows the bandage
100 applied on a patient's head, wherein the straps 180 have been
tensioned and fastened to provide a lateral adjustment of the main
body 110 against the periphery of the head, over the ears. As
shown, the straps 180 extend along either side of the head in a
generally symmetrical fashion, along and parallel to the rim 126,
providing a snug adjustment of the cap. Since the straps 180
achieve a uniform pressure along a respective substantial length L,
the straps 180 create no pressure points and cause no added
discomfort to the patient. In addition, a syringe 400 has been
inserted through one of the discrete through ports 114 by passing
the syringe tip 410 through the opening 164 of the third layer 160,
the corresponding elongated space 152 of the second layer 150 and
the corresponding opening 144 of the first layer 140. Operation of
the syringe 400 causes a medicine contained in the syringe 400 to
be delivered directly into the cavity 122 and onto a wound without
having to move the bandage 100 to a different position on the
patient's head or without having to partially or completely remove
the bandage 100 from the patient's head.
[0073] The illustration of FIG. 5 shows the bandage 100 placed
covering a stump, where placement is again carried out by correctly
positioning the cap-shaped main body 110, and tightening and
attaching the straps 180 along and parallel to the rim 126. The
medical professional has further inserted a drainage tube 420
through one of the elongated through ports 112, which has been
previously formed or opened by tearing a length of the perforated
seams 142, 162 of the first and third layers 140, 160 in order to
open a passageway through the opened seams 142, 162 and the
elongated space 152. Direct access to a wound in order to remove
body fluids from the wound is therefore achieved without having to
re-position or remove the bandage 100, thus preventing further
discomfort to the patient.
[0074] Therefore, a single device is provided that can be
intuitively and universally used to cover either a wound on the
head or a wound on a stump. In addition, the device is extremely
easy and convenient to use, saving precious medical treatment time
and allowing a more rapid care of severe wounds, and ongoing
treatment of chronic wounds. Being able to dress a wound more
rapidly is greatly beneficial for the patient, as bleeding can be
controlled much sooner by means of the immediate stop effect
provided by the direct placement of the bandage; in addition, the
wound exposure time is cut down, thereby reducing the risk of
infection.
[0075] The illustrations of FIGS. 7 through 10 present a bandage
200 in accordance with a second exemplary embodiment of the
invention. Like features of the bandage 200 of FIGS. 7 through 10
and the bandage 100 of FIGS. 1 through 6 are numbered the same
except preceded by the numeral `2`. As in the previous embodiment,
the bandage 200 comprises a main body 210 having a front side 230,
a rear side 232, a right side 234, a left side 236, an inner
surface 220, an outer surface 224, an internal cavity 222 for
receiving a head or stump, and a bottom edge or rim 226 delimiting
a bottom opening for inserting the head or stump into the cavity
222. The main body 210 further includes several elongated through
ports 212 and two punctual or discrete through ports 214 providing
access to the internal cavity 222 from outside the bandage 200. Two
straps 280 extend from the rear side 232 to the front side 230 of
the main body 210, along the left and right sides 236, 234,
respectively, and along the rim 226 and parallel to the rim 226.
Similarly to the previous embodiment, a first end 282 of the
adjustment straps 280 is fixedly or non-disconnectably attached to
the main body rear side 232 and an opposite second end 284 is
disconnectably attachable to the main body front side 230. The
straps 280 are disconnectably attachable to the main body 210 by a
hook-and-loop connection formed by a first hook-and-loop element
290 forming part of the strap 280 and a compatible second
hook-and-loop element 292 included in the main body 210. As shown
in FIG. 7, the first and second hook-and-loop elements 290, 292 are
elongated and arranged parallel to the rim 226, thereby increasing
the adjustment range provided by the straps 280 and thus favoring
that a single-size bandage 200 is usable on different head sizes or
body parts.
[0076] The main body 210 is formed of an innermost soft,
skin-compatible first layer 240, an outermost non-permeable third
layer 260, and an intermediate second layer. As shown in FIG. 8,
the second layer of the present embodiment is a flexible bladder
270, i.e. a flexible non-permeable layer comprising an internal
cavity 272 for housing at least one solid substance, at least one
liquid substance, at least one gaseous substance, or combinations
thereof. A bladder access port 274 provides access to the internal
cavity 272, for instance in order to inject air or warm water into
the internal cavity 272. The bladder access port 274 of the present
embodiment is initially closed by a perforable or tearable membrane
276, which can optionally include an X-shaped score or other
predefined score to facilitate tearing or perforating the membrane
276 with a syringe or manually, to name a few examples. In some
embodiments, the internal cavity 272 can be provided with isolated
or non-isolated compartments to promote a uniform distribution of
the substance(s) within the cavity.
[0077] The illustrations of FIGS. 8 through 10 depict several usage
scenarios of the bandage of FIG. 7. Referring initially to FIG. 8,
the bandage 200 is shown fitted onto a patient's head in order to
provide an adjusted dressing of the head in the event of a trauma
or wounds. The illustration of FIG. 9, in turn, shows the bandage
200 fitted onto a patient's head and a syringe 400 having
perforated and penetrated a discrete through port 214 and in the
process of administering a liquid medicine (not shown) onto a wound
430. Finally, the illustration of FIG. 10 presents a further
application in which the bandage 200 has been fitted onto a
patient's head and a nozzle or syringe 400 has perforated the
membrane 276 (FIG. 8) and penetrated the bladder access port 274
and has injected air into the inner flexible bladder 270, causing
the flexible bladder 270 to expand and the bandage 200 to compress
the head of the patient, such as to stop bleeding of a wound 430.
In turn, a drainage tube 420 has been inserted through a discrete
through port 214 in order to remove body fluids from a wound 430.
In a further application, not shown in the drawings, a vacuum tube
could be inserted into a discrete through port 214 and a suction
force could be applied through the vacuum tube in order to create a
vacuum inside the bandage 200, thereby removing air from the
internal cavity of the main body and thus reducing the risk of
contamination of the wound as well as increasing compression of the
wound.
[0078] In some embodiments, the internal cavity 272 of the flexible
bladder 270 can hold solid substances for specific treatment
purposes. For instance and without limitation, the bandage 200 can
be manufactured in such a way that the internal cavity 272 is
marketed containing solid substances that are configured to
exothermically react with a liquid (e.g., water). Thus, when
placing the bandage 200 on the patient's head or limb, the medical
professional can inject water through the bladder access port 274
to cause an exothermic reaction between the water and the solid
substances and thus warm the bandage 200.
[0079] Alternative embodiments are contemplated in which the main
body includes both an internal flexible bladder and an internal
absorbent layer, in which case the flexible bladder is preferably
arranged externally to the absorbent layer. The main body is
therefore capable of absorbing and retaining body fluids from a
wound and simultaneously compressing the wound, for instance to
stop the wound from bleeding.
[0080] The illustrations of FIGS. 11 through 13 present a bandage
500 in accordance with a third exemplary embodiment of the
invention. Like features of the bandage 500 of FIGS. 11 through 13
and the bandage 100 of FIGS. 1 through 6 are numbered the same
except preceded by the numeral `5`. As shown, the bandage 500
comprises a cap-shaped main body 510. Similarly to previous
embodiments, the main body 510 has an inner surface (not shown, but
otherwise similar to inner surface 120 of bandage 100 shown in FIG.
1), an outer surface 524, and an inner cavity (not shown, but
otherwise similar to inner cavity 120). The inner cavity is
delimited by the inner surface and is configured to at least
partially receive a head, limb, stump, finger or protruding body
part. In the present figures, for instance, the bandage 500 is
shown applied to a leg stump 440 such that an end of the leg stump
440 is received within the inner cavity of the main body 510.
Similarly to previous embodiments, the main body 510 comprises a
skin-compatible first layer 540, a second layer 550, and a
non-permeable third layer 560. The first layer 540 is arranged
closer to the inner cavity than the third layer 560, and the second
layer 550 is sandwiched between the first layer 540 and the third
layer 560 and comprises at least one space 552 through which the
first and third layers 540, 560 directly face one another.
Similarly to previous embodiments, at least one through port 512,
514 is arranged at said at least one space 552, for accessing the
inner cavity of the main body 510 from outside the main body 510
and through the first, second and third layers 540, 550 and 560, or
for stabilizing or supporting a drain or tubing passing through the
port.
[0081] As further shown in FIG. 11, two straps 580 extend along
opposite sides of the main body 510, at or near an edge or rim 526
of the main body 510. Similarly to previous embodiments, a first
end (not shown) and an opposite second end 584 of the adjustment
straps 580 are non-disconnectably and disconnectably attached to
the main body 510, respectively. The second end 584 of the straps
580 is disconnectably attachable to the main body 510 by a
hook-and-loop connection formed by a first hook-and-loop element
590 forming part of the strap 580 and a compatible second
hook-and-loop element 592 included in the main body 510. As shown
in FIG. 11, the first and second hook-and-loop elements 590, 592
can be elongated and arranged at or near the rim 526.
[0082] In a first illustrative use of the bandage 500, as shown in
FIG. 11, the straps 580 can be normally arranged to extend along
the main body 510 and the first hook-and-loop element 590 of each
strap 580 can engage with the corresponding second hook-and-loop
element 592 on the main body 510, without the straps 580 engaging
with each other. In a second illustrative use of the bandage 500,
shown in FIG. 12, the straps 580 are wound or twisted with one
another and the second end 584 of each strap 580 is oriented
rearward, toward the corresponding fixed, first end of the strap
580, with the second ends 584 attached to the second hook-and-loop
elements 592 on the main body 510. This second application allows
for a tighter fitting of the bandage 500 onto the stump or other
body part. In a third illustrative application of the bandage 500,
shown in FIG. 13, the straps 580 are tied into a knot 586,
providing an even tighter fitting of the main body 510 onto the
stump or other body part. Though not specifically shown in FIG. 13,
the first hook-and-loop elements 590 carried by the straps 580 can
be optionally attached to the second hook-and-loop elements 592 on
the main body 510.
[0083] In other words, the straps of the present embodiment or
other embodiments not only may present varying lengths but also are
susceptible to being tied or arranged in different ways to provide
various effects (e.g. varying-strength tourniquet effects) on the
body part to be covered by the bandage.
[0084] The illustration of FIG. 14 presents a bandage 600 in
accordance with a fourth illustrative embodiment of the invention.
Like features of the bandage 600 of FIG. 14 and the bandage 100 of
FIGS. 1 through 6 are numbered the same except preceded by the
numeral `6`.As shown, the bandage 600 comprises a cap-shaped main
body 610 having an inner surface (not shown, but otherwise similar
to inner surface 120 of bandage 100 shown in FIG. 1), an outer
surface 624, and an inner cavity (not shown, but otherwise similar
to inner cavity 120) which is delimited by the inner surface.
Similarly to previous embodiments, the main body 610 comprises a
skin-compatible first layer 640, a second layer 650, and a
non-permeable third layer 660. The first layer 640 is arranged
closer to the inner cavity than the third layer 660, and the second
layer 650 is sandwiched between the first layer 640 and the third
layer 660 and comprises at least one space 652 through which the
first and third layers 640, 660 directly face one another.
Similarly to previous embodiments, at least one through port 612 is
arranged at said at least one space 652, for accessing the inner
cavity of the main body 610 from outside the main body 610 and
through the first, second and third layers 640, 650 and 660, or for
stabilizing or supporting a drain or tubing passing through the
port. A single strap 680 extends along the main body 610, at or
near an edge or rim 626 of the main body 610 and attaches to the
main body 610 by a hook-and-loop fastener. The main body 610 of the
present embodiment is, however, smaller in size than previous
embodiments, and is configured to at least partially cover a user's
finger 450.
[0085] The drawing of FIG. 15 shows a bandage 700 in accordance
with a fifth illustrative embodiment of the invention. Like
features of the bandage 700 of FIG. 15 and the bandage 100 of FIGS.
1 through 7 are numbered the same except preceded by the numeral
`7`. As shown, the bandage 700 comprises a cap-shaped main body 710
having an inner surface (not shown, but otherwise similar to inner
surface 120 of bandage 100 shown in FIG. 1), an outer surface 724,
and an inner cavity (not shown, but otherwise similar to inner
cavity 120) which is delimited by the inner surface. Similarly to
previous embodiments, the main body 710 comprises a skin-compatible
first layer 740, a second layer 750, and a non-permeable third
layer 760. The first layer 740 is arranged closer to the inner
cavity than the third layer 760, and the second layer 750 is
sandwiched between the first layer 740 and the third layer 760 and
comprises at least one space 752 through which the first and third
layers 740, 760 directly face one another. Similarly to previous
embodiments, at least one through port 712 is arranged at said at
least one space 752, for accessing the inner cavity of the main
body 710 from outside the main body 710 and through the first,
second and third layers 740, 750 and 760, or for stabilizing or
supporting a drain or tubing passing through the port. At least one
strap 780 extends along the main body 710, at or near an edge or
rim 726 of the main body 710 and attaches to the main body 710 by a
hook-and-loop fastener.
[0086] Similarly to the bandage 600 of FIG. 14, the main body 710
of the present embodiment is relatively small in size and is
configured to at least partially cover a user's finger 450. In a
further aspect of the invention, the bandage 700 of the present
invention is provided with an adjustable height which allows a user
to easily and conveniently alter the overall height of the main
body 710, such as to adjust the main body 710 to different finger
lengths, wounds or areas to be treated, etc. Specifically, the main
body 710 can include several body portions which initially come
attached to one another and can be separated from one another to
reduce the size of the main body 710 if so required by the medical
condition to be treated. For instance and without limitation, the
main body 710 of the present embodiment includes comprises two body
portions, i.e. a first body portion 716 and a second body portion
718. The first body portion 716 is cap-shaped and the second body
portion 718 is annularly-shaped and extends along an edge of the
first body portion 716. The first body portion 716 and second body
portion 718 are initially attached to one another or
integrally-formed with one another, with a scored or tear line or
area 719 formed between the first and second body portions 716 and
718 to facilitate removing the second body portion 718 if not
needed. In operation, the bandage 700 is placed on a person's
finger 450 and, if the finger 450 is relatively long or the wound
to be treated is relatively small and arranged at a tip of the
finger, the second body portion 718 may be ripped or torn off the
first body portion 716 along the tear area 719 and the second body
portion 718 may be removed from the finger 450 and either discarded
or used for alternative purposes (e.g. as a tourniquet). To
illustrate this process of removing the second body portion 718,
the drawing of FIG. 15 shows the second body portion 718 arranged
in a partially removed position shown in broken lines and indicated
with reference numeral 718'. As further shown in the drawing, one
or both of the main body portions can be provided with one or more
straps 780. The one or more straps 780 of the second body portion
718 are removable jointly with the second body portion 718.
Furthermore, the at least one space 752 and corresponding through
ports 712 can extend through one or both main body portions, in
different implementations of the invention; for instance, in the
example shown in the drawing, the spaces 752 and corresponding
through ports 712 extend along both the first body portion 716 and
the second body portion 718. Finally, it must be noted that,
similarly to other aspects of the invention, the aspect of having
the main body formed by two or more separable parts can be applied
to any one of the other embodiments described herein.
[0087] The illustrations of FIGS. 16 and 17 show a bandage 800 in
accordance with a sixth exemplary embodiment of the invention. Like
features of the bandage 800 of FIGS. 16 and 17 and the bandage 100
of FIGS. 1 through 7 are numbered the same except preceded by the
numeral `8`. Similarly to previous embodiments, the medical bandage
800 comprises a main body 810 having an inner surface 820, an outer
surface 824 and an inner cavity 822 delimited by the inner surface
820 for at least partially receiving a body part such as, but not
limited to, a head 460. Similarly to previous embodiments, the main
body 810 includes a skin-compatible first layer 840, a second layer
850, and a non-permeable third layer 860, the second layer 850
being sandwiched between the first and third layers 840 and 860 and
comprising at least one space 852 through which the first and third
layers 840 and 860 directly face one another. At least one through
port 812 is arranged at said at least one space 852 (for instance,
by perforating the first and third layers 840 and 860 in the area
of the space 852, for example at or along a perforated or tearable
seam 842), for accessing the inner cavity 822 of the main body 810
from outside the main body 810 and through the first, second and
third layers 840, 850 and 860, or for stabilizing or supporting a
drain or tubing passing through the port 812.
[0088] Similarly to the embodiment of FIGS. 1 through 3, the main
body 810 of the present embodiment is comprised of several body
portions. Specifically, the main body 810 is formed of a
longitudinal body portion 854 and two opposite side body portions
856. As shown in FIG. 17, the longitudinal body portion 854 is
configured to cover the head 450 or other protruding body part in a
front-to-back arrangement, while the two opposite side body
portions 856 are configured to be arranged on opposite sides of the
longitudinal body portion 854 and cover sides of the head 450 or
body portion, with the longitudinal and side body portions 854 and
856 forming a cap- or dome-shaped structure. In the present
embodiment, however, at least one of the side body portions 856 is
pivotably attached to the longitudinal body portion 854 along a
hinge section 855, such that the pivotable side body portion 856
can pivotably switch between the aforementioned cap-shaped
arrangement of FIG. 17 and an open position, shown in FIG. 16, in
which the pivotable side body portion 856 is pivoted away from the
cavity 822 and towards the longitudinal body portion 854.
[0089] This pivotable connection between the longitudinal body
portion 854 and one or, preferably, both side body portions 856
facilitates donning the bandage 800 on the head 450 of a person in
a supine position, as shown in FIGS. 16-17. Specifically, as shown
in broken lines in FIG. 16, a medical professional may initially
place the bandage 800 in the aforementioned open position
(indicated with reference numeral 800'), and tuck a rear end 857 of
the longitudinal body portion 854 underneath the person's head 450.
Next, the medical professional may pull a front end 858 of the
longitudinal body portion 854 towards the person's forehead, as
indicated by arrow B, and place the longitudinal body portion 854
on or along the person's head 450 as shown. Once the longitudinal
body portion 854 is deployed on the head 450, the side body
portions 856 can be pivoted towards the head 450 as indicated by
arrows C and placed on or near the sides of the head 450 as shown
in FIG. 17. Finally, the straps 880 can be extended over the
longitudinal and side body portions 854 and 856 to retain the side
body portions 856 in the position of FIG. 17, i.e. to maintain the
main body 810 in cap-shaped form and secure the main body 810 to
the head 450.
[0090] Because one or both of the side body portions 856 of the
bandage 800 of FIG. 16 are pivotable relative to the longitudinal
body portion 854, and both body portions 854, 856 are flexible or
malleable (similarly to the rest of embodiments), the bandage 800
can adopt a myriad of positions and shapes by deforming the
longitudinal body portion 854 and/or the side body portions 856,
and pivoting the side body portions 856 relative to the
longitudinal body portion 854. For instance and without limitation,
as shown in FIG. 18, the longitudinal body portion 854 and side
body portions 856 can adopt an extended position such that the main
body 810 is relatively planar and can be used to cover a wider area
of a person's body such as, but not limited to, the chest or
thorax. For example, the bandage 800 can include an insulating
material such as, but not limited to, biaxially-oriented
polyethylene terephthalate (e.g., Mylar.RTM.), such as in the
second layer 850, allowing the bandage to be used over the chest to
prevent pneumothorax.
[0091] The illustrations of FIGS. 19 through 22 show a bandage 900
in accordance with a seventh exemplary embodiment of the invention.
Like features of the bandage 900 of FIGS. 19 through 22 and the
bandage 100 of FIGS. 1 through 7 are numbered the same except
preceded by the numeral `9`. As best shown in FIG. 20, similarly to
previous embodiments, the medical bandage 900 comprises a main body
910 having an inner surface 920, an outer surface 924 and an inner
cavity 922 delimited by the inner surface 920 for at least
partially receiving a body part. Similarly to previous embodiments,
the main body 910 includes a skin-compatible first layer 940, a
second layer 950, and a non-permeable third layer 960, the second
layer 950 being sandwiched between the first and third layers 940
and 960 and comprising at least one space 952 through which the
first and third layers 940 and 960 directly face one another. At
least one elongated through port 912 and/or discrete through port
914 is arranged at said at least one space 952, for accessing the
inner cavity 922 of the main body 910 from outside the main body
910 and through the first, second and third layers 940, 950 and
960, or for stabilizing or supporting a drain or tubing passing
through the port 912; for instance, the elongated through port 912
can be formed by perforating the first and third layers 940 and 960
in the area of the space 952, such as at or along a perforated or
tearable seam 942.
[0092] With continued reference to FIG. 20, the bandage 900 of the
present embodiment further comprises at least one sensor 970, such
as a bioelectric sensor, configured to monitor one or more vital
signs such as, but not limited to, pulse (heart rate), oxygen
saturation, temperature, pressure (bandage pressure), blood
pressure, moisture, bacterial concentration, presence of
cerebrospinal fluid (CSF), ECG (electrocardiogram),
electroencephalogram (EEG), thermal imaging, or sleep, or to
monitor other physiological or cognitive status. The sensor 970 may
be in wired or wireless (e.g., infrared or Bluetooth) communication
with a monitoring device (e.g., smartphone 900 shown in FIG. 22).
In some embodiments, the sensor 970 can include a color-coded light
visible to the medical professional and indicative of the sensor
measurements, for quick assessment of patient status.
[0093] In some embodiments, the sensor can be embedded in the
bandage. In other embodiments, such as the present embodiment, the
sensor 970 can be detachably connectable to the bandage 900, and
more specifically, to the main body 910 of the bandage 900. For
example, as shown in FIGS. 20 and 21, the sensor 970 can be
selectively attached or detached from the sensor connector 958 in
the main body 910.
[0094] The illustration of FIG. 19 shows an enlarged view of the
sensor 970. As can be seen, the sensor 970 can include a bottom
platform 972, a top platform 974 and a stem 976 extending between
the bottom and top platforms 972 and 974. A sensor circuit 978 can
be provided on at least one of the bottom platform 972, the top
platform 974 and the stem 976 to be placed near a site of a pulse
or site for wound and patient monitoring. For example, in the
present embodiment, the sensor circuit 978 is arranged in the
bottom platform 972, which is configured to be placed closer to the
body part that will be covered by the bandage 900, allowing the
sensor 970 to be placed directly over the site to be monitored
(e.g., wound 462 shown in FIG. 22). The top and bottom platforms
972 and 974 may be round, as shown, or present alternative shapes
such as square, rectangular, oval, etc.
[0095] In some embodiments, when a sensor 970 is not plugged into
the sensor connector 958, the sensor connector 958 may also be used
as a discrete port and serve the same purposes as the discrete
through port 914 and other discrete through ports described herein
with reference to the remaining embodiments. In other words, one or
more discrete through ports provided in the bandage may be used as
a sensor connector for detachably receiving a sensor.
[0096] In operation, as shown in FIG. 22, the bandage 900 is fitted
onto the head 460 of a user to cover wound 462. The sensor
connector 958 is oriented towards the wound 962 and the sensor 970
is inserted or plugged into the sensor connector 958 such that the
sensor circuit 978 faces the wound 962. The sensor circuit 978
captures one or more measurements. A wired or wireless transmitter
(not shown) comprised in the sensor transmits the measurement to a
smartphone 990 or other monitoring device running a software
application or program configured to process, store and/or
visualize or present the measured data on a screen or other user
interface, or carry out other operations with the measured
data.
[0097] Alternative embodiments and uses of the invention are
contemplated. For instance, the bandage can be used to cover
alternative body parts to those shown in the drawings and/or
described herein. Alternatively or additionally, the number and/or
length of straps included in the bandage may vary.
[0098] In the foregoing specification, specific embodiments of the
present invention have been described. However, one of ordinary
skill in the art appreciates that various modifications and changes
can be made without departing from the scope of the present
invention as set forth in the claims below. Accordingly, the
